Barcode Scanner

Zia Barcode Scanner enables you to scan the most commonly used linear and 2D barcode formats and decode the encoded data. Barcode Scanner can detect formats like Codabar, EAN-13, ITF, UPC-A, QR Code, and more.

You can provide an input file of the format .jpg/.jpeg or .png. Refer to the API documentation for the request and response formats.

You can specify the barcode format using setFormat. If you enter the format as ALL, Barcode Scanner automatically detects the format. It provides the decoded information as the response.
